ECHA advises registrants to regularly check the use maps library. Since May 2020, three sectors have updated or further completed their use map packages:

• The European Crop Protection Association (ECPA), updated its use map and specific environmental release categories (sPERCs), and made the respective Chesar files available;
• The European Solvents Industry group (ESIG), updated its use map Chesar file, sPERCs Chesar file and sPERCs background documents; and
• The European Petroleum Refiners Association (Concawe), made its use map, use map Chesar file and related sectorial guidance available.
